Kafka AVRO Schema Ingestion: Named types are not parsed completely

[vladimirivkovic]

Describe the bug A named type is used to specify the type for multiple fields in a record.

Sample AVRO schema:

{
  "namespace": "com.sample.avro.schema",
  "type": "record",
  "name": "Pyramid",
  "fields": [
    {
      "name": "a",
      "type": {
      	"type": "record",
      	"name": "Point3D",
      	"fields": [
          { "name": "x", "type": "double" },
          { "name": "y", "type": "double" },
          { "name": "z", "type": "double" }
        ]
      }
    },
    { "name": "b", "type": "Point3D" },
    {
      "name": "c",
      "type": ["null", "Point3D"]
    },
    { "name": "d", "type": "Point3D" }
  ]
}

After running Kafka ingestion with Schema Registry enabled, the following schema is shown in DataHub:

To Reproduce Steps to reproduce the behavior:

1. Create a Kafka topic named pyramid with the AVRO schema specified above
2. Run the UI ingestion
3. Search for pyramid topic and open it
4. See error in Schema tab

Expected behavior It is expected that fields b and d have the same structure as the field a - three sub-fields.

Desktop (please complete the following information):

• OS: Ubuntu 22.04
• Browser: firefox
• Version 0.12.1

Additional context The same issue is noticed for both UI ingestion and custom ingestion using Python SDK and the schema_util.avro_schema_to_mce_fields method.

For this case, it seems that commenting out the else statement here solves the problem.
